正确答案及解析
正确答案
解析
商品的价值是凝结在商品中的无差别的人类劳动，因此商品价值量的大小是由生产商品耗费的劳动量的多少决定的，而衡量劳动量的天然尺度是劳动时间，所以商品的价值量取决于生产该种商品的社会必要劳动时间。“物联网”没有减少生产商品所需要的社会必要劳动时间，因而也就没有减少商品的价值量。故C项不选。商品只要进行流通和交换，其所有权和使用权就会发生分离。没有“物联网”的时候，也同样发生分离。故D项不选。

方式二：纵观中国历史上的改革，有成功的，例如商鞅变法使秦国慢慢强大起来，北魏孝文帝改革促进民族融合；也有失败的，例如我们今天学习的戊戌变法，虽然失败了，但是客观上也推动了中国社会的发展和进步。是符合历史发展潮流的。

If you don′t think a phone is the rightgift for a lover, the smart choice this year is a smart phone.
For people who don′t read instructions
The easiest-to-use phone is the iPhone. It′sthat has pushed it to the No.1 selling position, surpassing the Motorola Razr.The iPhone′s touch screen is easy to operate and it′s also easy to customize (用户化). The iPhone can run allsorts of applications such as those help you to lose weight, identify a song onthe radio, find a restaurant or do many other things.
For the futurist
The T-Mobile G1 is very popular as it is thefirst phone to offer a Google browser, meaning that you′re getting the real webon your phone, but it′s the phone′s potential that qualifies it for the futurist.The exciting applications are interesting, but they don′t always work smoothly.Sometimes it is hard to use the applications it comes with. The system shouldimprove as it becomes more popular, so it holds great promise. With fewrestrictions on the design of applications for the phone,
the G1 could be the first phone toincorporate (整合) some of the coolest.
For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back. It stillincorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people. The 3.25-inch is bright anddetailed and it′s a decent size for watching videos on the go.
For the Luddite (反对技术进步的人)
For those who can′t handle buttons and newfeatures, there is the Samsung Jitterbug Dial. Some people are Luddites whojust want a few large buttons to make calls. That′s it, just calls. That makesit even easier to use an iPhone.
